I suppose that is a possibility, I was just concerned because of the issue I had with my first colony. One was sneezing, and I hoped it would go away, then next thing I know she was dead, then the next about a week later, and so on and so forth.... Idk what caused it. The second colony I bought is doing great, no issues. But this newest when I heard one sneeze I got scared because of my first experience and that my established colony could get sick.
